彭博社 (Bloomberg / Péngbóshè) is an American privately held financial software, media, and data company. Bloomberg L.P. was founded by Michael Bloomberg (current Mayor of New York City).
Why it is blocked: A number of foreign media outlets are blocked on Weibo, including Voice of America, the World Journal, and Epoch Times, but Bloomberg is notable in that it might be considered an apolitical corporation. Chinese authorities blocked Bloomberg’s website in June 2012 after it published an exposé on the wealth accumulated by future president Xi Jinping’s family, but this search block on Weibo predates that article. Currently, one is unable to make a post that contains 彭博社. Trying to do so will return the error message, “Sorry, this content violates ‘Sina Weibo’s Community Guidelines’ or related regulations and policies.” [Status - 11/25/11: blocked; 2/5/12: blocked; 3/12/12: blocked]
